To all whom it may concern:

Be it known that I, Rosoon L. I'IEAFER, a citizen of the United States, residing at Bloomington, in the county of McLean and State of Illinois, have invented a new and useful Improvement in Pipe or Tile Cutting Machines, of which the following is a specification.

This invention relates generally to sewer pipe or tile cutting machines, the object being to provide a machine for use in cutting what is commonly called a snout or jointtile for sewerpipes and drain-tile connections.

It is also the object of the invention to pro vide a machine of this kind which can be quickly and easily adjusted for accurately cutting pipes or tiles of various sizes and at any desired angle.

\Vith these objects in View the invention consists in the novel features of construction, combination, and arrangement, all of which will be fully described hereinafter and pointed out in the claims.

In the drawings forming a part of this specification, Figure 1 is a perspective View of a machine embodying my invention. Fig. 2 is a top plan view of the same. Fig. 3 is a detail view of the bow and cutting-wire carried thereby. Fig. at is a detail sectional view on the line 4 4 of F 3. Fig. 5 is an inverted detail perspective showing the manner of adjusting the table and the adjustable bracket carried by said table. Fig. 6 is a detail perspective view of one of the adjustable boxcs carrying the pivoted bearing. Fig. 7 is a detail perspective view of said bearing. Fig. 8 is a sectional view of the box, the bear ing being shown in dotted lines.

In carrying out my invention I employ a base A, which is preferably mounted upon castings or wheels A, so that the machine can be easily moved to any part of the building. Rigidly attached to the base A are the standards B and C, the standards B being arranged at one end and the standards 0 at the opposite end, the standards C being somewhat higher than the standards B, as most clearly shown. The standards B and C are connected at their upper ends by means of blocks B and C, respectively, through which work the slide-rods D, carrying the sliding boxes E at their lower ends, said boxes fitting between the standards, as most clearly shown, and bifurcated, as shown at E, and pivoted in each box is the bearing F. Set-screws D pass laterally through the blocks B and O for the purpose of holding the rods D at any desired point of adjustment.

G indicates a bow-shaped frame having longitudinal portions H extending in reverse directions from the opposite ends, said j ournaled portions H turning in the pivoted bearings F, and connected to the parallel mem bers of the bow-shaped frame are the adjustable arms I, to which the cutting-wire K is attached, said arms I being slotted longitudinally, as shown at I, and secured at any point of adjustment by means of the bindingscrew 1*.

The standards B and C are connected adjacent their lower ends by means of a hori zontal plate L, slotted longitudinally, as shown at L, and sliding upon this plate L is the supporting-table M, having guide-ribs M, and which bear against the side edges of the plate L and cause the table to travel in a straight line. The bolt M", carrying a nut M, is attached to the table and works in the slot M, so that the table can be fastened at any desired point of adjustment. The table has a fixed gage-bracket N secured at one end, and at one side is the adjustable bracket 0, the reduced end of which slides in the slot 0 and is secured by means of the nut 0 said bracket 0 being adjustable toward or away from the transverse line 1, marked upon the table, and working in this bracket 0 is a rod P, having a head P at its inner end, which serves as a gage and against which the pipe or tile to be cut is adapted to rest, said head P being adjustable toward or away from the longitudinal line 2, marked upon the table, and a set-screw P is employed for locking the rod P at any desired point of adjustment.

\Vhen it is desired to cut a pipe or tile, the adjustable bracketOis adjusted to the proper position with reference to the line 1 and the rod P adjusted to its proper position with reference to the line 2, said adjustments being governed by the diameter of the pipe or tile to be cut. The boxes E are then ad justed to their proper positions, which of course will be determined upon the length of the joint desired and also whether it is to be a straight oint or an oblique joint, it being understood that for a straight joint the bow will be held in a true horizontal position, whereas if an oblique joint one box or the other will be elevated, thereby throwing the bearings upon an oblique line. The arms I are adjusted to suit the diameter of the pipe to be cut, and after the pipe has been arranged upon the table and held in contact with the gages the bow is rocked or swung to a half circle, forcing the Wire K through the pipe or tile, it being understood that said pipe or tile is in a green or unburned condition. The adjustment of the wire is of course made with reference to the diameter of the pipe to which the pipe being cut is to be fitted, and after the wire has been adjusted the various sizes of pipes or tiles can be quickly and easily cut by simply adjusting the gages upon the table.

It will also be seen that in order to cut the pipe or tile in a different angle it is only necessary to adjust the bearings, which can be quickly and easily done by simply moving the boxes up or down and locking the rods D.

It will thus be seen that I provide an exceedingly cheap, simple, and efficient construction of machine capable of carrying out all of the objects hereinbefore mentioned.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine of the kind described, the horizontally-adjustable table and means for locking the same, the fixed gage carried by the table and an adjustable gage arranged upon the table and at a right angle to the fixed gage.

2. In a machine of the kind described, the table, the fixed gage carried by the table, an adjustable bracket sliding in a slot in the table and a rod adjustable in the bracket and carrying a head at its inner end.

3. In a machine of the kind described, the combination with the standards, of the laterally-adjustable table, the adjustable boxes and means for locking the same, the bearing pivoted in said adjustable boxes, the bowframe having journals turning in the bearings and the cutting-wire adjustably connected to the bow-frame.

4. In a machine of the kind described, the combination with the base and standards, of the supportingplate, the table adjustable therein, and carrying the fixed gage, the adjustable gage carried by the table, the boxes having guide-rods and means for securing them, the pivoted bearings carried by the boxes, the bow-frame having journals, the adjustable arms and the cutting-wire con nected to said arms all arranged as described.
